One embodiment of the subject disclosure includes a tangiblecomputer-readable storage device comprising instructions, which whenexecuted by a device processor cause the device processor to performoperations. The operations comprise sending a first request for serviceto a management server remote from the device; receiving from themanagement server an authentication management function and anencryption key generator for execution by a secure element and anencryption engine for execution by a secure device processor, to causethe secure element and the secure device processor to authenticate eachother using a mutual authentication keyset, wherein the secure elementand the secure device processor are separate from each other and coupledto the device processor; authenticating a user using a user interfacekeyset, wherein user credentials are verified by the authenticationmanagement function; sending a second request to establish acommunication session with a remote second device, wherein the secondrequest is initiated by the secure device processor; and communicatingwith the second device via a communication channel established using anapplication server. The secure element, the secure device processor andthe device processor each have a security level associated therewith,and the security level associated with the secure device processor isintermediate between that of the secure element and that of the deviceprocessor. The secure element is a universal integrated circuit card,the secure element and the secure device processor form a secure serviceplatform separate from the device processor, the mutual authenticationkeyset is provided to the secure service platform by the managementserver, and the management server transmits information to the secureservice platform using a remote management keyset. The mutualauthentication keyset, the user interface keyset and the remotemanagement keyset are distinct keysets.

In accordance with an embodiment of the disclosure, FIG. 1 depicts anarrangement 100 of a communication device (CD) connected to a networkand provided with a secure services platform enabling authentication ofother communication devices and encrypted communication with thosedevices. It will be appreciated that the communication device may be anydevice, including a user device that has a secure element and a securedevice processor and thus has secure communication capability. The term“user,” in this embodiment, refers to a human user of the communicationdevice. In other embodiments, the user can be a machine that exchangesdata with the communication device after being authenticated to thecommunication device. Communication device 102 includes device processor104, secure device processor 106 and a secure element 108. In thisembodiment, secure element 108 is a universal integrated circuit card(UICC). The UICC is a secure computing platform and offers a high levelof security for storing encryption keys, authentication credentials, andthe like. The UICC may be removable from the device. Alternatively, theUICC may be embedded in the device and not removable. In otherembodiments, the secure element can be placed on a memory card or anembedded chip. The secure device processor (SDP) 106 is logically and/orphysically separate from the device processor 104, and is connected toboth the device processor and the UICC. In this embodiment, the SDPoffers a higher level of security than the device processor 104, andstores and executes secure applications. The SDP can, for example, runapplications in a trusted execution environment. The secure element andsecure device processor together form a secure services platform 110resident on device 102. In this embodiment secure element 108, securedevice processor 106 and device processor 104 each have a security levelassociated therewith, and the security level associated with the securedevice processor 106 is intermediate between that of the secure element108 and that of the device processor 104. The secure device processorand secure element use mutual authentication, as described in moredetail below.

The secure element and secure device processor communicate with amanagement server 120, located remotely from device 102. The remotemanagement server is a platform for provisioning and managingapplications in the secure element and secure device processor. Theremote management server also manages data (such as keys, credentials,etc.) that are used by the applications.

In this embodiment, user device 102 is a wireless communication deviceconnected to a cellular network 122. Network 122 can also be a WiFinetwork. In other embodiments, device 102 can be connected to otherdevices via a wired connection through a computer. In still otherembodiments, user devices may communicate with each other usingBluetooth, infrared communications (IRDa) or near field communications(NFC). A communication session between user devices, wherein informationis transferred between the users, can be effected by a wide variety ofarrangements. As explained in detail below, a secure application server(SAS) is used in some embodiments to establish a secure communicationsession between devices. However, a secure application server is notused in embodiments where the communication session is established in apeer-to-peer manner, such as in Bluetooth, IRDa or NFC.

FIG. 2 is a schematic illustration 200 showing details of a secureservices platform 110, according to an embodiment of the disclosure. Thesecure element 108 (in this embodiment, a UICC) contains anauthentication management function 202 and a real-time encryption keygenerator 204. The authentication management function 202 provides allauthentication services for the device. Specifically, the authenticationmanagement function supports the mutual authentication of devices,supports the mutual authentication of the device with the SAS, andsupports the mutual authentication of the device with the remotemanagement server. As shown in FIG. 2, the authentication managementfunction includes a user authentication service 212 for authenticatingthe user to the device and a network authentication service 214 forauthenticating the device to network equipment. The real-time encryptionkey generator 204 supplies encryption keys to the real-time encryptionengine 206 which is located in the SDP 106. The real-time encryptionengine 206 encrypts and decrypts user information transmitted to or froma bearer path 216 that terminates at another user device, and mayencrypt and decrypt information transmitted on a signaling path 218 tothe network. In another embodiment, the encryption engine can be loadedon a second secure element, separate from the secure element 108.

The remote management server 120 performs a remote provisioning andmanagement function 210 to load applications and content into the UICCand SDP. In this embodiment, the remote management server provisions theauthentication management function 202 and real-time encryption keygenerator 204 on the UICC 108, and provisions the real-time encryptionengine 206 on the SDP 106. This is done securely by the use of one ormore remote management keysets. Before the secure services platform 110can be used for communication, the SDP must be authenticated by theUICC. This is done using a UICC-SDP keyset. The UICC-SDP keyset may beprovisioned remotely by the remote management server or locally by anauthorized user. In this embodiment, after the UICC and SDP are mutuallyauthenticated using the UICC-SDP keyset, they communicate via asignaling path 208 within the secure services platform 110.Alternatively, the path between the UICC 108 and the SDP 106 may gothrough the device processor 104 rather than directly between the UICCand the SDP.

FIG. 3 schematically illustrates a network architecture 300 forfacilitating secure communication between two user devices, according toan embodiment of the disclosure. In this embodiment, end-to-end securitycan be provided to end users by using the UICC and the SDP as a securityplatform in conjunction with a secure application server (SAS). A firstuser device 301 and a second user device 302 are each managed andprovisioned by remote management server 320. Remote management keyset321 is used to securely transmit information from the remote managementserver to the user devices. (In other embodiments, devices 301, 302 canbe provisioned by separate remote management servers, generally usingdifferent keysets.) Each user device has a UICC and a SDP mutuallyauthenticated by a UICC-SDP keyset, shown schematically at 311 and 312respectively.

Each device must also have a user (or, in other embodiments, a machinethat interacts with the device) authenticated to that device. Userauthentication is performed by the authentication management function ofthe UICC of each device, using a user interface keyset 313, 314respectively. User authentication may involve many types of credentials:pin numbers, fingerprints, retinal scans, voice recognition, etc. Theuser interface keysets 313, 314 may be provisioned by the remotemanagement server or locally by an authorized user.

In this embodiment, a secure application server 330 is used to establisha communication session between user devices 301, 302. The remotemanagement server 320 provisions the secure application server 330 withuser information related to the secure communication service. The secureapplication server and the UICC of user device 301 mutually authenticateeach other using a signaling authentication keyset 331; the secureapplication server and the UICC of user device 302 mutually authenticateeach other using a signaling authentication keyset 333. The secureapplication server can then establish secure signaling sessions with theuser devices 301, 302, using signaling encryption keysets 332, 334respectively. The authentication and encryption keysets are provisionedto the secure application server by the remote management server.

The secure application server 330 creates an unsecure communicationsession between user devices 301, 302 over a bearer path 340. The bearerpath can include, but is not limited to, UMTS, LTE, and WiFi. Mutualauthentication between the user devices is performed using a bearer pathauthentication keyset 341. If increased security is desired, thecommunication between devices can be encrypted using a bearer pathencryption keyset 342.

FIG. 4 is a flowchart 400 showing a procedure for establishing acommunication session between two user devices using a secureapplication server, in accordance with an embodiment of the disclosure.Upon receiving a request for service (step 402), the remote managementserver 320 downloads programs and content to user devices 301, 302 toallow the user devices to support a secure communication service thatincludes real-time encryption and authentication services (step 404).For each of the user devices, the remote management server loads thereal-time encryption engine into the secure device processor (SDP) ofthe device (e.g. smartphone, M2M device), the authentication managementfunction to the secure element (e.g. a UICC), and the real-timeencryption key generator to the secure element.

In step 406, the remote management server provisions the secureapplication server (SAS) 330 with information regarding the user devices301, 302. Remote management keyset(s) 321 are used to securely transmitinformation from the remote management server to the user devices and tothe secure application server 330. This process involves mutualauthentication and encryption.

After the user devices are provisioned, the UICC and SDP within eachdevice mutually authenticate each other (step 408). In this embodiment,this is done using UICC-SDP keysets 311, 312. In general, the UICC-SDPkeysets used in the two user devices will be distinct keysets. The userof device 301 then authenticates with the device using user interfacekeyset 313 (step 410). User authentication may be performed using avariety of credentials, including pin number, fingerprint, retinal scan,etc. The user's credentials are verified by the authenticationmanagement function within the UICC of device 301. In this embodiment,wherein signaling to a secure application server is performed, the eachof the users must authenticate with their device before establishment ofa secure signaling channel to the SAS.

Secure application server 330 is used to set up a secure communicationpath between the two users through their respective devices (user device301 and user device 302). The SDP of user device 301 initiates a requestfor a secure signaling session to the secure application server 330(step 412). The secure application server 330 and the UICC of userdevice 301 mutually authenticate each other using a signalingauthentication keyset 331. The secure application server 330 isauthenticated by the authentication management function within the UICCof user device 301.

Once the user device 301 and the secure application server 330 aremutually authenticated, an encrypted channel is established between themusing the signaling encryption keyset 332 (step 414). The encryption anddecryption is performed by the real-time encryption engine in the SDP ofuser device 301. The signaling encryption keyset 332 is provided to theSDP by the real-time encryption key generator within the UICC of userdevice 301. The request for the session (originating from device 301 instep 412) is passed to the secure application server 330.

The user of device 302 must authenticate with the device before asignaling session can take place between device 302 and the secureapplication server 330. This is done (step 416) using user interfacekeyset 314, which may be different from user interface keyset 313. Theuser authentication process is performed by the authenticationmanagement function within the UICC of user device 302. The secureapplication server 330 then instructs user device 302 to establish asecure signaling session with the SAS (step 418). The secure applicationserver 330 and the UICC of user device 302 mutually authenticate eachother using signaling authentication keyset 333 (which may be differentfrom signaling authentication keyset 331). The secure application server330 is authenticated by the authentication management function withinthe UICC of user device 302.

Once mutually authenticated, an encrypted channel is established betweenuser device 302 and the secure application server 330 (step 420), usingsignaling encryption keyset 334 (which may be different from signalingencryption keyset 332). The encryption and decryption is performedwithin the by the real-time encryption engine in the SDP of user device302. The signaling encryption keyset 334 is provided to the SDP by thereal-time encryption key generator within the UICC of user device 302.The request for the session (originating from device 301 in step 412) ispassed from the secure application server 330 to user device 302.

In step 422, user device 302 is notified by the secure applicationserver 330 that a session request has been made.

Mutual authentication is then performed directly between user device 301and user device 302 using the bearer path authentication keyset 341(step 424). This authentication process is performed by theauthentication management functions within the UICC of user device 301and user device 302.

FIG. 5 is a flowchart 500 showing a process, in accordance with anembodiment, to establish an encrypted communication session between userdevices 301 and 302. This process is performed after the devices havemutually authenticated in accordance with a secure signaling sessionusing SAS 330 and a bearer path 340 has been established, as describedabove with reference to FIG. 4.

User devices 301 and 302 communicate via bearer path 340 (step 502). Ifeither user wishes to increase the security of the communication (step504), that user's device sends a notice to the other device that abi-directional encrypted session is desired (step 506). The SDP of eachuser device requests a bearer path encryption keyset from the real-timeencryption key generator within the UICC of that device (step 508). Theencryption and decryption is performed by the real-time encryptionengine in each SDP (step 510). The devices 301, 302 then send notices tothe respective users that each user is authenticated and that thecommunication session is encrypted (step 512).

FIG. 6 schematically illustrates a network architecture 600 forfacilitating secure communication between two user devices, according toanother embodiment of the disclosure. In this embodiment, an applicationserver is used to establish an unsecure communication channel; securesignaling between the devices and the application server is notperformed. Authentication of the user devices to each other andencryption of the communication channel (bearer path) can be performeddirectly between the user devices.

The first user device 601 and the second user device 602 are eachmanaged and provisioned by remote management server 620. Remotemanagement keyset 621 is used to securely transmit information from theremote management server to the user devices. Each user device has aUICC and a SDP authenticated by a UICC-SDP keyset, shown schematicallyat 611 and 612 respectively.

Each device must also have a user authenticated to that device. (Inother embodiments, the device can interact with a machine instead of auser.) User authentication is performed by the authentication managementfunction of the UICC of each device, using a user interface keyset 613,614 respectively. User authentication may involve many types ofcredentials: pin numbers, fingerprints, retinal scans, voicerecognition, etc. The user interface keysets 613, 614 may be provisionedby the remote management server or locally by an authorized user.

An application server is used to establish an unsecure communicationsession over a bearer path 640 between the user devices 601, 602.(Alternatively, the unsecure communication session can be establisheddirectly between the devices, for example in a peer-to-peerarrangement.) The bearer path can include, but is not limited to, UMTS,LTE, and WiFi. If increased security is desired, mutual authenticationbetween the user devices can be performed using a bearer pathauthentication keyset 641. The communication between devices 601, 602can also be encrypted using a bearer path encryption keyset 642.

FIG. 7 is a flowchart 700 showing a procedure for establishing acommunication session between two user devices, in accordance with theembodiment shown in FIG. 6. Upon receiving a request for service (step702), the remote management server 620 downloads programs and content touser devices 601, 602 to allow the user devices to support a securecommunication service that includes real-time encryption andauthentication services (step 704). For each of the user devices, theremote management server loads the real-time encryption engine into thesecure device processor (SDP) of the device (e.g. smartphone, M2Mdevice), the authentication management function to the secure element(e.g., a UICC), and the real-time encryption key generator to the secureelement. Remote management keyset(s) 621 are used to securely transmitinformation from the remote management server to the user devices. Thisprocess involves mutual authentication and encryption.

After the user devices are provisioned, the UICC and SDP within eachdevice mutually authenticate each other (step 706). In this embodiment,this is done using UICC-SDP keysets 611, 612. In general, the UICC-SDPkeysets used in the two user devices will be distinct keysets.

In this embodiment, an application server is used to set up an unsecurecommunication path between the two users through their respectivedevices (user device 601 and user device 602). The SDP of user device601 begins the process of establishing communication with device 602 bydirecting a request for a communication session secure signaling sessionto the application server (step 708). It will be appreciated that inother embodiments, use of an application server is optional in settingup an unsecure communication path. For example, to establish apeer-to-peer communication session using Bluetooth or NFC, anapplication server would not be used.

In step 710, user device 602 is notified by the application server thata session request has been made.

An unsecure communication channel (bearer path 640) is establishedbetween user devices 601, 602 (step 712). The devices are not requiredto be authenticated to each other to establish the unsecure bearer path.Both users are notified that the communication channel has beenestablished and is unsecure (step 716). In this embodiment, since thecommunication channel is unsecure, the users are not required toauthenticate with their respective devices prior to the establishment ofthe bearer path.

FIG. 8 is a flowchart 800 showing a process, in accordance with anembodiment, to establish communication with increased security betweenuser devices 601 and 602 after an unsecure bearer path has beenestablished.

User devices 601 and 602 communicate via unsecure bearer path 640 (step802). During the communication session, either user can determine (step804) that the other user should be authenticated. Alternatively, thisdetermination can be made by an automated process. If increased securityis desired, the users authenticate with their respective devices (steps806, 808), and the devices perform mutual authentication using bearerpath authentication keyset 641 (step 810). The users must beauthenticated with their respective devices prior to the mutualauthentication of the devices to each other. This authentication processis performed by the authentication management functions within thesecure element of the respective user devices. If the users werepreviously authenticated, they may be prompted to re-authenticate.

If encryption of the communication session is also desired (step 812),one user device (device 601 in this example) notifies the other thatbi-directional encryption is to be performed (step 814). The SDP of eachuser device requests a bearer path encryption keyset from the real-timeencryption key generator within the secure element of that device (step816). The encryption and decryption is performed by the real-timeencryption engine in each SDP (step 818). The devices 601, 602 then sendnotices to the respective users that each user is authenticated and thatthe communication session is encrypted (step 820).

FIG. 9 depicts an illustrative embodiment of a communication system 900employing an IP Multimedia Subsystem (IMS) network architecture tofacilitate the combined services of circuit-switched and packet-switchedsystems. Communication system 900 can be overlaid or operably coupledwith the architecture of FIG. 3 or FIG. 6 as another representativeembodiment of the disclosure. For example, any or all of the remotemanagement server 320, the secure application server 330, user device301 and user device 302 can be part of, or coupled to, the communicationsystem. In particular, device 905 can comprise a secure element such asa UICC; a secure device processor (SDP) separate from the secureelement; a memory to store executable instructions; and a deviceprocessor separate from the secure device processor (see FIG. 1),wherein in response to executing the instructions the device processorsends a first request for service to a management server and receivesfrom the management server an authentication management function and anencryption key generator for execution by the secure element and anencryption engine for execution by the secure device processor, to causethe secure element and the secure device processor to mutuallyauthenticate each other using a UICC-SDP keyset (see FIG. 2), andwherein the device authenticates a user of the device using a userinterface keyset to verify user credentials by the authenticationmanagement function; sends a second request for a secure signalingsession to a secure application server remote from the device, receivesfrom the secure application server a first authentication signal,wherein the secure application server is authenticated by theauthentication management function using a signaling authenticationkeyset; communicates with the secure application server via a firstencrypted channel using a first signaling encryption keyset, whereinencryption and decryption of communications over the first encryptedchannel is performed by the encryption engine and the first signalingencryption keyset is generated by the encryption key generator; andsends a third request to the secure application server to establish acommunication session with a second device (see FIG. 3).

Communication system 900 can comprise a remote management server 930,located remotely from user communication device 905. In an embodiment,server 930 performs remote provisioning and management functions (shownschematically at 931) for user communication devices. User communicationdevice 905 can perform an authentication management and real-timeencryption key generation functions (shown schematically at 933).Communication system 900 can also comprise a Home Subscriber Server(HSS) 940, a tElephone NUmber Mapping (ENUM) server 935 and othernetwork elements of an IMS network 950. The IMS network 950 canestablish communications between IMS-compliant communication devices(CDs) 901, 902, Public Switched Telephone Network (PSTN) CD 903, andcombinations thereof by way of a Media Gateway Control Function (MGCF)920 coupled to a PSTN network 960. The MGCF 920 need not be used when acommunication session involves IMS CD to IMS CD communications. Acommunication session involving at least one PSTN CD may utilize theMGCF 920.

IMS CDs 901, 902 can register with the IMS network 950 by contacting aProxy Call Session Control Function (P-CSCF) which communicates with aninterrogating CSCF (I-CSCF), which in turn, communicates with a ServingCSCF (S-CSCF) to register the CDs with the HSS 940. To initiate acommunication session between CDs, an originating IMS CD 901 can submita Session Initiation Protocol (SIP INVITE) message to an originatingP-CSCF 904 which communicates with a corresponding originating S-CSCF906. The originating S-CSCF 906 can submit the SIP INVITE message to oneor more application servers (ASs) 917 that can provide a variety ofservices to IMS subscribers. An application server 917 can provideencryption and authentication functions (shown schematically at 932) forsignaling messages between user devices and the application server. TheIMS can support a secure application server as well as an applicationserver.

For example, the application servers 917 can be used to performoriginating call feature treatment functions on the calling party numberreceived by the originating S-CSCF 906 in the SIP INVITE message.Originating treatment functions can include determining whether thecalling party number has international calling services, call IDblocking, calling name blocking, 7-digit dialing, and/or is requestingspecial telephony features (e.g., *72 forward calls, *73 cancel callforwarding, *67 for caller ID blocking, and so on). Based on initialfilter criteria (iFCs) in a subscriber profile associated with a CD, oneor more application servers may be invoked to provide various calloriginating feature services.

Additionally, the originating S-CSCF 906 can submit queries to the ENUMsystem 935 to translate an E.164 telephone number in the SIP INVITEmessage to a SIP Uniform Resource Identifier (URI) if the terminatingcommunication device is IMS-compliant. The SIP URI can be used by anInterrogating CSCF (I-CSCF) 907 to submit a query to the HSS 940 toidentify a terminating S-CSCF 914 associated with a terminating IMS CDsuch as reference 902. Once identified, the I-CSCF 907 can submit theSIP INVITE message to the terminating S-CSCF 914. The terminating S-CSCF914 can then identify a terminating P-CSCF 916 associated with theterminating CD 902. The P-CSCF 916 may then signal the CD 902 toestablish Voice over Internet Protocol (VoIP) communication services,thereby enabling the calling and called parties to engage in voiceand/or data communications. Based on the iFCs in the subscriber profile,one or more application servers may be invoked to provide various callterminating feature services, such as call forwarding, do not disturb,music tones, simultaneous ringing, sequential ringing, etc.
